Here is a Sunderland blog post heavily featuring CD's impact -

"One player ran the show for Sunderland in possession, and it was our rookie defender Callum Doyle. As you can see in the visual, big Doyler is connected to Hoffmann, Flanagan, Neil, Embleton and Cirkin.
The 17-year-old actually made 19.70% of Sunderland’s passes - that’s almost 1 in 5."
There are graphics on that blog post that reflect what I saw watching the full match replay the other day. The field tilts toward CD as they start out of the back with possession. Sunderland look to get him the ball then get open because he'll zing it to you wherever you are on the pitch. Its also interesting that his new left fb wingman is a 19yo England youth named Dennis Cirkin who is starting to impress. Cirkin played for the U20s with Mcatee vs Romania recently, to give context. Can't hurt CD's dev to have a non-lumberjack nearby in possession.
